這里用的是MyEclpise的自帶的MAVEN插件。
Maven最好配置成你自己安裝的那個，MyEclipse自帶會有些許Bug。
用nexus代理Maven的中央倉庫，setting.xml的配置文件修改內(nèi)容如下：
<mirrors>
<mirror>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<name>Nexus Mirror</name>
<url>http://localhost:8081/nexus/content/groups/public</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<repositories>
<repository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://central</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfile>
</activeProfiles>
http://localhost:8081/nexus/content/groups/public 是倉庫組的地址。
打下MyEclipse新建工程的界面，選擇Maven下的Maven Project，打開如下圖的向?qū)В?br />
這里我們要選中create a simple project。
點擊下一步，填寫GAV相關(guān)內(nèi)容。
點擊完成后，我們就已經(jīng)成功創(chuàng)建了一個Maven project了。
工程的默認目錄結(jié)構(gòu)如下：
所有的Java源文件都要寫在src/main/java目錄下，所有的測試類都要寫在src/test/java下面，這是Maven的默認值。
此時,pom.xml里只有默認的屬性
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.test</groupId>
<artifactId>test</artifactId>
<version>0.0.1-SNAPSHOT</version>
</project>
這是最精簡的pom.xml了。
這時我們加入junit的支持，新建一個測試類。
在項目上右鍵Maven-Add Dependency，顯示如下界面：
輸入junit加入測試支持類庫。
在src/test/java下新建一個測試類如下：
package com;
import org.junit.Test;
public class TestRun
{
@Test
public void testA()
{
System.out.println("test a method ");
}
@Test
public void testB()
{
System.out.println("test b method ");
}
}
右鍵Run As ----- Maven test，進行測試，顯示結(jié)果如下：

ok,一個基本的maven項目已經(jīng)構(gòu)建完成。我們還可以將現(xiàn)存的java項目利用myclipse方便的轉(zhuǎn)換成maven project，此部分內(nèi)容我們在下一節(jié)里討論。
